Thank you to everyone who replied to my request for information about windmills in Arundel. I have sent a copy of my picture to the Sussex Windmill website and asked for their opinion, as the photo they have is not exactly the same as the one in my picture. My research interests in Sussex are the STURT family of Arundel and Stopham and the STEVENS family of Arundel and Swanage, Dorset. Ros Dunnico.
